database-build

Why we included this project

database.build puts a real Postgres database in your browser tab, and it arrives as a full web app you can use right away rather than a library to integrate. Each sandbox you create runs a fresh PGlite instance, the WASM build of Postgres, so queries execute locally with genuine SQL semantics and no container or remote server behind them. Data is saved to IndexedDB, so your work survives a refresh. Every database also comes with an LLM beside it: drop a CSV in and it builds the table on the fly, or ask questions about the data and get back a generated report, chart, or even a database diagram. That combination makes it a fast way to explore a dataset or sketch a schema before moving to hosted Postgres, without standing up any infrastructure to get there.
